Automating NES Games, Code Review Tool, SaaS KPIs, and No Free Lunch

  1. A General Technique for Automating NES Gamessoftware that learns how to play NES games and plays them automatically, using an aesthetically pleasing technique. With video, research paper, and code.
  2. rietveld — open source tool like Mondrian, Google’s code review tool. Developed by Guido van Rossum, who developed Mondrian. Still being actively developed. (via Nelson Minar)
  3. KPI Dashboard for Early-Stage SaaS Startups — as Google Docs sheet. Nice.
  4. Life Without Sleep — interesting critique of Provigil as performance-enhancing drug for information workers. It is very difficult to design a stimulant that offers focus without tunnelling – that is, without losing the ability to relate well to one’s wider environment and therefore make socially nuanced decisions. Irritability and impatience grate on team dynamics and social skills, but such nuances are usually missed in drug studies, where they are usually treated as unreliable self-reported data. These problems were largely ignored in the early enthusiasm for drug-based ways to reduce sleep. [...] Volunteers on the stimulant modafinil omitted these feedback requests, instead providing brusque, non-question instructions, such as: ‘Exit West at the roundabout, then turn left at the park.’ Their dialogues were shorter and they produced less accurate maps than control volunteers. What is more, modafinil causes an overestimation of one’s own performance: those individuals on modafinil not only performed worse, but were less likely to notice that they did. (via Dave Pell)

Street View Tiles Hacks, Policy Simulation, Map Tile Toolbox, and Connected Sensor Device HowTo

  1. HyperLapse — this won the Internet for April. Everyone else can go home. Check out this unbelievable video and source is available.
  2. Housing Simulator — NZ’s largest city is consulting on its growth plan, and includes a simulator so you can decide where the growth to house the hundreds of thousands of predicted residents will come from. Reminds me of NPR’s Budget Hero. Notice that none of the levers control immigration or city taxes to make different cities attractive or unattractive. Growth is a given and you’re left trying to figure out which green fields to pave.
  3. Converting To and From Google Map Tile Coordinates in PostGIS (Pete Warden) — Google Maps’ system of power-of-two tiles has become a defacto standard, widely used by all sorts of web mapping software. I’ve found it handy to use as a caching scheme for our data, but the PostGIS calls to use it were getting pretty messy, so I wrapped them up in a few functions. Code on github.
  4. So You Want to Build A Connected Sensor Device? (Google Doc) — The purpose of this document is to provide an overview of infrastructure, options, and tradeoffs for the parts of the data ecosystem that deal with generating, storing, transmitting, and sharing data. In addition to providing an overview, the goal is to learn what the pain points are, so we can address them. This is a collaborative document drafted for the purpose of discussion and contribution at Sensored Meetup #10. (via Rachel Kalmar)

Electric Monks, Moore's Law's Death Spiral, Trafficking Technology, and Product Management

  1. Automated Essay Grading To Come to EdX (NY Times) — shortly after we get software that writes stories for us, we get software to read them for us.
  2. AMD Calls End of Moore’s Law in Ten Years (ComputerWorld) — story based on this video, where Michio Kaku lays out the timeline for Moore’s Law’s wind-down and the spin-up of new technology.
  3. Addressing Human Trafficking Through Technology (danah boyd) — technologists love to make tech and then assert it’ll help people. Danah’s work on teens and now trafficking steers us to do what works, rather than what is showy or easiest.
  4. Product Management (Rowan Simpson) — hand this to anyone who asks what product management actually is. Excellent explanation.

Mozilla Payments, Firefox Cleans Cookies, Lost: One Web Please Return to Those Who Love It, and 3D from Spaaaaace

  1. mozpaya JavaScript API inspired by google.payments.inapp.buy() but modified for things like multiple payment providers and carrier billing. When a web app invokes navigator.mozPay() in Firefox OS, the device shows a secure window with a concise UI. After authenticating, the user can easily charge the payment to her mobile carrier bill or credit card. When completed, the app delivers the product. Repeat purchases are quick and easy.
  2. Firefox Looks Like it Will Reject Third-Party Cookies (ComputerWorld) — kudos Mozilla! Now we’ll see whether such a cookie policy does deliver a better user experience. Can privacy coexist with a good user experience? Answers on a tweet, please, to @radar.
  3. How We Lost the Web (Anil Dash) — excellent talk about the decreasing openness and vanishing shared culture of the web. See also David Weinberger’s transcription.
  4. 3D From Space Shuttle Footage? — neat idea! Filming in 3D generally requires two cameras that are separated laterally, to create the parallax effected needed for stereoscopic vision. Fortunately, videos shot from Earth orbit can be converted to 3D without a second camera, because the camera is constantly in motion.

Hi-Res Long-Distance, Robot Ants, Data Liberation, and Network Neutrality

  1. Millimetre-Accuracy 3D Imaging From 1km Away (The Register) — With further development, Heriot-Watt University Research Fellow Aongus McCarthy says, the system could end up both portable and with a range of up to 10 Km. See the paper for the full story.
  2. Robot Ants With Pheromones of Light (PLoS Comp Biol) — see also the video. (via IEEE Spectrum’s AI blog)
  3. tabula — open source tool for liberating data tables trapped inside PDF files. (via Source)
  4. There’s No Economic Imperative to Reconsider an Open Internet (SSRN) — The debate on the neutrality of Internet access isn’t new, and if its intensity varies over time, it has for a long while tainted the relationship between Internet Service Providers (ISPs) and Online Service Providers (OSPs). This paper explores the economic relationship between these two types of players, examines in laymen’s terms how the traffic can be routed efficiently and the associated cost of that routing. The paper then assesses various arguments in support of net discrimination to conclude that there is no threat to the internet economy such that reconsidering something as precious as an open internet would be necessary.

Bootstrap Fun, Digital Public Library, Snake Robots, and Aboriginal Data

  1. geo-bootstrap — Twitter Bootstrap fork that looks like a classic geocities page. Because. (via Narciso Jaramillo)
  2. Digital Public Library of America — public libraries sharing full text and metadata for scans, coordinating digitisation, maximum reuse. See The Verge piece. (via Dan Cohen)
  3. Snake Robots — I don’t think this is a joke. The snake robot’s versatile abilities make it a useful tool for reaching locations or viewpoints that humans or other equipment cannot. The robots are able to climb to a high vantage point, maneuver through a variety of terrains, and fit through tight spaces like fences or pipes. These abilities can be useful for scouting and reconnaissance applications in either urban or natural environments. Watch the video, the nightmares will haunt you. (via Aaron Straup Cope)
  4. The Power of Data in Aboriginal Hands (PDF) — critique of government statistical data gathering of Aboriginal populations. That ABS [Australian Bureau of Statistics] survey is designed to assist governments, commentators or academics who want to construct policies that shape our lives or encourage a one-sided public discourse about us and our position in the Australian nation. The survey does not provide information that Indigenous people can use to advance our position because the data is aggregated at the national or state level or within the broad ABS categories of very remote, remote, regional or urban Australia. These categories are constructed in the imagination of the Australian nation state. They are not geographic, social or cultural spaces that have relevance to Aboriginal people. [...] The Australian nation’s foundation document of 1901 explicitly excluded Indigenous people from being counted in the national census. That provision in the constitution, combined with Section 51, sub section 26, which empowered the Commonwealth to make special laws for ‘the people of any race, other than the Aboriginal race in any State’ was an unambiguous and defining statement about Australian nation building. The Founding Fathers mandated the federated governments of Australia to oversee the disappearance of Aboriginal people in Australia.

Master Coding, Rethinking Textbooks, Blocking Open Access, VPN from your Pi

  1. Analyzing mbostock’s queue.js — beautiful walkthrough of a small library, showing the how and why of good coding.
  2. What Job Would You Hire a Textbook To Do? (Karl Fisch) — notes from a Discovery Education “Beyond the Textbook” event. The issues Karl highlights for textbooks (why digital, etc.) are there for all books as we create this new genre.
  3. Neutralizing Open Access (Glyn Moody) — the publishers appear to have captured the UK group implementing the UK’s open access policy. At every single step of the way, the RCUK policy has been weakened. From being the best and most progressive in the world, it’s now considerably weaker than policies already in action elsewhere in the world, and hardly represents an increment on their 2006 policy. What’s at stake? Opportunity to do science faster, to provide source access to research for the public, and to redirect back to research the millions of pounds spent on journal subscriptions.
  4. Turn the Raspberry Pi into a VPN Server (LinuxUser) — One possible scenario for wanting a cheap server that you can leave somewhere is if you have recently moved away from home and would like to be able to easily access all of the devices on the network at home, in a secure manner. This will enable you to send files directly to computers, diagnose problems and other useful things. You’ll also be leaving a powered USB hub connected to the Pi, so that you can tell someone to plug in their flash drive, hard drive etc and put files on it for them. This way, they can simply come and collect it later whenever the transfer has finished.

Machine Learning Demos, iOS Debugging, Industrial Internet, and Deanonymity

  1. MLDemosan open-source visualization tool for machine learning algorithms created to help studying and understanding how several algorithms function and how their parameters affect and modify the results in problems of classification, regression, clustering, dimensionality reduction, dynamical systems and reward maximization. (via Mark Alen)
  2. kiln (GitHub) — open source extensible on-device debugging framework for iOS apps.
  3. Industrial Internet — the O’Reilly report on the industrial Internet of things is out. Prasad suggests an illustration: for every car with a rain sensor today, there are more than 10 that don’t have one. Instead of an optical sensor that turns on windshield wipers when it sees water, imagine the human in the car as a sensor — probably somewhat more discerning than the optical sensor in knowing what wiper setting is appropriate. A car could broadcast its wiper setting, along with its location, to the cloud. “Now you’ve got what you might call a rain API — two machines talking, mediated by a human being,” says Prasad. It could alert other cars to the presence of rain, perhaps switching on headlights automatically or changing the assumptions that nearby cars make about road traction.
  4. Unique in the Crowd: The Privacy Bounds of Human Mobility (PDF, Nature) — We study fifteen months of human mobility data for one and a half million individuals and find that human mobility traces are highly unique. In fact, in a dataset where the location of an individual is specified hourly, and with a spatial resolution equal to that given by the carrier’s antennas, four spatio-temporal points are enough to uniquely identify 95% of the individuals. We coarsen the data spatially and temporally to find a formula for the uniqueness of human mobility traces given their resolution and the available outside information. This formula shows that the uniqueness of mobility traces decays approximately as the 1/10 power of their resolution. Hence, even coarse datasets provide little anonymity. These findings represent fundamental constraints to an individual’s privacy and have important implications for the design of frameworks and institutions dedicated to protect the privacy of individuals. As Edd observed, “You are a unique snowflake, after all.” (via Alasdair Allan)

Titan Improved, Security Tweeps, Probabilistic Programming, and 3D-Printable Optics

  1. Titan 0.3 Out — graph database now has full-text, geo, and numeric-range index backends.
  2. Mozilla Security Community Do a Reddit AMA — if you wanted a list of sharp web security people to follow on Twitter, you could do a lot worse than this.
  3. Probabilistic Programming and Bayesian Methods for Hackers (Github) — An introduction to Bayesian methods + probabilistic programming in data analysis with a computation/understanding-first, mathematics-second point of view. All in pure Python. See also Why Probabilistic Programming Matters and Trends to Watch: Logic and Probabilistic Programming. (via Mike Loukides and Renee DiRestra)
  4. Open Source 3D-Printable Optics Equipment (PLOSone) — This study demonstrates an open-source optical library, which significantly reduces the costs associated with much optical equipment, while also enabling relatively easily adapted customizable designs. The cost reductions in general are over 97%, with some components representing only 1% of the current commercial investment for optical products of similar function. The results of this study make its clear that this method of scientific hardware development enables a much broader audience to participate in optical experimentation both as research and teaching platforms than previous proprietary methods.
